Maxlite brand 15 Watt compact fluorescent reflector lamp. R30 size and shape replaces up to 75 Watt BR30 lamp and fits into the recessed lighting fixtures used most often in both homes and businesses. Warm white color and high color rendering mean you'll never know the difference, at least until you get your electric bill.

NOT RECOMMENDED for use in enclosed fixtures or for use with control devices such as sensors or dimmers, may shorten lamp life

Energy Used

A rating, expressed in watts, to indicate the rate at which a lamp consumes energy. Also known as wattage value.

15 Watts

Incandescent/Halogen Equivalent

The wattage value of an incandescent or halogen lamp of similar brightness.

Incandescent/Halogen Equivalent

75 Watts

Volts

A measure of "electrical pressure" between two points. The voltage specification of an incandescent lamp is the electrical "pressure" required to drive it at its designed point. The "voltage" of a ballast (e.g. 120 V) refers to the line voltage coming from the power source and is connected to the ballast.

Base

The end (or ends) of the lamp that fits into the socket.

Bulb Shape

The description of the general appearance of a lamp/bulb consists of a letter(s) followed by a number. The letter indicates the shape of the bulb and the number relates to the diameter of the bulb in eighths of an inch. For example, a common household bulb is the A-19. The bulb is "A" shape and the diameter would be nineteen 8ths of an inch, or 2 3/8".

Bulb Color

The color of the light produced by a bulb

CRI

Color Rendering Index is an international system used to rate a lamp's ability to render object colors. The higher the CRI (based upon a 0-100 scale) the richer and more accurately colors generally appear. CRI differences among lamps are not usually visible to the eye unless the difference is more than 3-5 points.

CRI

84

Color Temperature (Kelvin)

An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four digit number followed by (k), such as 2700k. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors. Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).

Color Temperature (Kelvin)

2700

Brightness (Lumens)

A rating of the initial light output of a bulb, rated after 100 hrs of operation. Lumens are a measure of how much light falls on one square foot of area, one foot away from the light source.

Bulb Finish

The surface finish of a bulb, which may affect the quality of the light emitted.

Average Rated Life (hr)

A measurement of the average length of time, between first use and the point when 50% of the lamps tested have stopped functioning, , using an operating cycle of 3 hours on, 20 minutes off.

Average Rated Life (hr)

10000

Length (in)

Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.

Length (in)

5.6

Diameter (in)

Light bulbs: a measurement of a bulb's width taken at the widest point of the bulb. Fixtures: the measurement across the widest point of a circular fixture.

This bulb takes almost a full minute to achieve maximum brightness. Not real useful unless you are turning on lights but don't mind bumping into things in the dim light for the first minute. Probably better suited to industry where business lights are turned on at the beginning of the day and are never shut off.

These lamps were used in recessed can fixtures in brand new modular cabins. We installed approximately 75 lamps throughout 24 cabins and had absolutely no problems with them. We are constantly researching ways of saving energy costs, and these defintely will help.

I've read the following: Outdoor useCFLs are generally not designed for outdoor use and some will not start in cold weather. CFLs are available with cold-weather ballasts, which may be rated to as low as −23 °C (−10 °F).[83] Light output drops at low temperatures.[84] Cold-cathode CFLs will start and perform in a wide range of temperatures due to their different design.

This bulb has a reliable operating temperature range of 0 Degrees to 100 Degrees. There are some CFL's out there that are rated to -20 Degrees Fahrenheit. Even with being rated for colder temperatures, the start up time and performance is still affected when used in extremely cold temperatures.

This bulb can be used outdoors providing it is protected from the elements and not used in a totally enclosed fixture. If the bulb is exposed to moisture or used in an enclosed fixture where the heat is not able to escape it will affect the life and performance of the bulb. It is also recommended that the bulb not be used with photocells or timers.
